The 4D Camera: an 87 kHz direct electron detector for scanning/transmission electron microscopy
Peter Ercius, Ian J. Johnson, Philipp Pelz +19
We describe the development, operation, and application of the 4D Camera -- a 576 by 576 pixel active pixel sensor for scanning/transmission electron microscopy which operates at 8…
Uncovering polar vortex structures by inversion of multiple scattering with a stacked Bloch wave model
Steven E Zeltmann, Shang-Lin Hsu, Hamish G Brown +4
Nanobeam electron diffraction can probe local structural properties of complex crystalline materials including phase, orientation, tilt, strain, and polarization. Ideally, each dif…
Electric Field Control of Chirality
Piush Behera, Molly A. May, Fernando Gómez-Ortiz +18
Polar textures have attracted significant attention in recent years as a promising analog to spin-based textures in ferromagnets. Here, using optical second harmonic generation bas…
A single-projection three-dimensional reconstruction algorithm for scanning transmission electron microscopy data
Hamish G. Brown, Philipp M. Pelz, Shang-Lin Hsu +13
Increasing interest in three-dimensional nanostructures adds impetus to electron microscopy techniques capable of imaging at or below the nanoscale in three dimensions. We present…
Unexpected Giant Microwave Conductivity in a Nominally Silent BiFeO3 Domain Wall
Yen-Lin Huang, Lu Zheng, Peng Chen +10
Nanoelectronic devices based on ferroelectric domain walls (DWs), such as memories, transistors, and rectifiers, have been demonstrated in recent years. Practical high-speed electr…
Full Electroresistance Modulation in a Mixed-Phase Metallic Alloy
Z. Q. Liu, L. Li, Z. Gai +11
We report a giant, ~22%, electroresistance modulation for a metallic alloy above room temperature. It is achieved by a small electric field of 2 kV/cm via piezoelectric strain-medi…
An invisible non-volatile solid-state memory
J. Clarkson, C. Frontera, Z. Q. Liu +20
Information technologies require entangling data stability with encryption for a next generation of secure data storage. Current magnetic memories, ranging from low-density stripes…
Atomic-scale control of magnetic anisotropy via novel spin-orbit coupling effect in La2/3Sr1/3MnO3/SrIrO3 superlattices
Di Yi, Jian Liu, Shang-Lin Hsu +11
Magnetic anisotropy (MA) is one of the most important material properties for modern spintronic devices. Conventional manipulation of the intrinsic MA, i.e. magnetocrystalline anis…
Single Crystal Functional Oxides on Silicon
Saidur Rahman Bakaul, Claudy Rayan Serrao, Michelle Lee +11
Single crystalline thin films of complex oxides show a rich variety of functional properties such as ferroelectricity, piezoelectricity, ferro and antiferromagnetism etc. that have…
180 degree Ferroelectric Stripe Nanodomains in BiFeO3 Thin Films
Zuhuang Chen, Jian Liu, Yajun Qi +7
There is growing evidence that domain walls in ferroics can possess emergent properties that are absent in bulk materials. For example, 180 domain walls in the ferroelectric-antife…
